title: Enzyme-linked immunosorbent assay compared with immunoprecipitation for serotyping Neisseria meningitidis and its use in demonstrating serotype polymorphism.
abstract: Rabbit antisera generated against 11 prototype strains of group B Neisseria meningitidis were tritiated by using the enzyme-linked immunosorbent assay and the Ouchterlony immunoprecipitation technique. The relative insensitivity of the immunoprecipitation technique in detecting antibody compared with the enzyme-linked immunosorbent assay was demonstrated. Cross-reactions within the group and among the 11 serotypes were characterized with respect to established serological techniques. Serotype polymorphism among the strains of N. meningitidis was demonstrated with the enzyme-linked immunosorbent assay.
